This project involves developing a web application and REST service to generate and display visualizations of ontologies. The web application will act as a client, calling the REST service and displaying the visualization outputs. The REST service will take ontology and profile data as input, along with a requested layer (conceptual, instance, or integrated) and output format. It will generate visualizations conforming to the VOWL specification and return them in SVG, PNG, JPG, or HTML formats. The project uses technologies like RDF, RDFa, RDF Schema, SPARQL, and OWL to represent and query ontology and instance data.
